您应该使用 ThemeOverlay.AppCompat.Dark.ActionBar 为您的工具栏风格。它集 colorControlNormal 到的android：textColorPrimary ，它是白色的深色主题。而且它不会从主要风格改变其他ATTRS。

 ＆LT; android.support.v7.widget.Toolbar的xmlns：程序=htt​​p://schemas.android.com/apk/res-auto＆GT;
    ...
    机器人：主题=@风格/ ThemeOverlay.AppCompat.Dark.ActionBar
    应用：popupTheme =@风格/ ThemeOverlay.AppCompat.Dark.ActionBar
＆LT; /android.support.v7.widget.Toolbar>
 

另外从你的主风格删除 drawerArrowStyle ，这是没有必要的。

OK, I know this is a trivial issue but for some reason it isn't working for me. I have done a lot of things suggested in other answers but in vain. My drawable folder has white color icons. I even tried to change it from styles.xml but that doesn't work either. I am testing it on my Lollipop device. Any help will be appreciated. Thanks in advance.

This is a portion of my manifest file.

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_drawer"
        android:label="@string/app_name" >
        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version"
            tools:replace="android:value" />

        <activity
            android:name=".Activity_Splash"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
                android:name=".Activity_test"
                android:launchMode="singleInstance"
                android:theme="@style/AppTheme.Base"
                android:windowSoftInputMode="stateHidden" />

And finally this is my style.xml. Similar is for v-21.

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowContentTransitions">true</item>
        <item name="android:windowAllowEnterTransitionOverlap">true</item>
        <item name="android:windowAllowReturnTransitionOverlap">true</item>
        <item name="android:actionMenuTextColor">#fff</item>
        <item name="colorPrimary">@color/ColorPrimary</item>
        <item name="colorPrimaryDark">@color/ColorPrimaryDark</item>
        <item name="drawerArrowStyle">@style/MyDrawerArrowToggle</item>
        <item name="windowActionBar">false</item>
        <item name="colorAccent">#fff</item>
        <item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
        <item name="android:windowSharedElementExitTransition">@android:transition/move</item>
</style>

You should use ThemeOverlay.AppCompat.Dark.ActionBar as your toolbar style. It sets colorControlNormal to android:textColorPrimary, which is white for dark themes. And it doesn't change other attrs from main style.

<android.support.v7.widget.Toolbar xmlns:app="http://schemas.android.com/apk/res-auto" >
    ... 
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
</android.support.v7.widget.Toolbar>

Also remove drawerArrowStyle from your main style, it's not needed.
